"N2 WAVEFORM DEMO CAPTURE USING BOTH CHANNELS" Recently had the opportunity to experiment with the N2 more and thought I would show how I use it to just as a first check tool when it comes to graphing capability compared to needing to grabbed a scope with higher sample rate speed and bandwidth. The wave forms I present here of exhaust camshaft signal in green obtained by back probing signal at the sensor and the red is ignition coil 1 control current ramp as reference point. To give more information first check PIC- 1 as it explains what green waveform is showing with N2......PIC- 2 IS N2 CAPTURE ...PIC-3 IS KNOWN GOOD WAVEFORM...PIC 4 & 5 N2 physical setup of current clamp on pcm control wire to ign coil 1 and both sets of lead share com port and other back probe red lead on volts port.

Test Purpose: The Amp Find mode allows you to Identify Amperage on a circuit. This feature is watching for a stabilized voltage reading over a certain threshold. If amperage is flowing through a fuse and the voltage drop is high enough the application will provide the “Amps Found” notification. If the “None” notification is showing the tool show no consistent voltage drop reading. Test Setup: - Sample rates: 256 (32) - Bottom Channel: Voltage DC or Auxiliary Voltage DC Top Channel: N/A Test Procedure: - Place Leads on tool to Voltage DC or Auxiliary Voltage DC - Use Probe Tips - Set the Data Intelligence menu to Amp Find - Put Probe Tips across the terminal tops of a single Fuse - Ensure probe tips are securely on top of fuse terminals for accurate reading. Any voltage reading = “Amps Found” This setting is highly sensitive so ghost voltage will identify as amps found. Once reading stabilize on circuit reading will be accurate. Recommendations: - Any draw over 30mA can kill battery over time. If Amp Find, “Finds Amps” shows it is suggested to verify the amperage reading is in alignment with what is expected. For example if a dome light is on, ensure the amperage draw is as expected. - Once a circuit is found with “amps found” you can verify circuit has amp draw by testing with fuse test. By selecting the fuse type and the fuse size. - Once amperage is found that is abnormal or not expected, you should confirm the circuit and components on that circuit using the vehicle fuse chart and a wiring diagram. Identify components/systems on associated circuit (check wiring diagrams). - If Amp draw is not expected or higher than anticipated then begin diagnosing those components/systems to see what is staying, shorted or drawing more than intended. - If you are unable to keep probes on fuses you can attach voltmeter to battery while diagnosing, enter graphing mode and watch the voltage rise or drop as you unplug and diagnose components.

Fuses readable by Curien Hub App today are: Test Procedure: - Sample rates: 256 (32) - Bottom Channel: Voltage DC or Auxiliary Voltage DC Top Channel: N/A - Place Leads on tool to Voltage DC or Auxiliary Voltage DC - Use Probe Tips - Set the Data Intelligence menu to Desired Fuse - Select the desired Standard fuse size and color - Put Probe Tips across the terminal tops of a single Fuse - Ensure probe tips are securely on top of fuse terminals for accurate reading. Note: reading may be off by as much as 5 - 15 mA as this is a calculated amperage reading. For amperage readings blow 10 amps to be accurate use in-series amp meter. Also using Auxiliary DC Voltmeter for this test instead of voltage DC will present a more accurate reading.
